Overview

• At a White House event, President Trump urged expectant mothers to avoid acetaminophen unless medically necessary and said clinicians should use the lowest effective dose for the shortest duration.
• HHS said the FDA will start a safety‑label update process for acetaminophen products and issue a physician letter advising clinicians to consider minimizing use during pregnancy for routine low‑grade fevers.
• The administration highlighted leucovorin, a folinic acid used for cancer and some anemias, as a potential therapy for autism symptoms, though current evidence comes from small studies and lacks large, rigorous trials.
• Researchers and major medical groups disputed a causal link, pointing to mixed findings and a large 2024 Swedish sibling study that found no increased autism risk from prenatal acetaminophen exposure.
• Tylenol maker Kenvue rejected any connection and its shares fell sharply on Monday, finishing down about 7% after earlier intraday losses.
